IMPROVEMENT IN MACHINERY FOR SCOURING- OR DRESSING HIDES.

The Schedule referred to in these Letters Patent and making part of the salme.

To all ,persons to whom these presents may come Be it known that we, CHARLES HOLMES and FRANK E. HOLMES, of Boston, in the county of Suffolk and State of Massachusetts, havemade a new and useful invention having reference to Machinery for Securing or Dressing Hides or Leather; and do hereby declare the same to be fully described as follows, reference being had to the accompanying drawing forming part of our specification, and of which- Figure l denotes a top view;

Figure 2, a side elevation; and Figure 3, a front elevation of our improved machine.

In our said machines the scrapers or to'ols have circular motions over the table, and are raised and lowered at intervals while in motion. rlhe rotary toolsupporter is also capable, with the tools, of being moved in any direction in a horizontal plane, in order to bring thetoolsvinto action on the various parts of a hide vor skin vwhile on the table, such table being stationary. o

In most, if not in all other machines for like pur-A poses, the table is movable under the tools, the latter having reciprocating motions attachedl to them.

In the drawing- A denotes the stationary table or bed for the skin or hide to rest on.

Over this table is the rotary `tool-supporter B, which -arranged as represented;

For revolving the tool-supporter B, there may be a hand-wheel or pulley, f, fixed on the upper part of the shaft b. About the said pulley, and another, at the joint of the arm, an endless belt may be carried.

Another endless belt may go around thepulley at the end joint, and also around another or drivingpulley arranged on the top of the post to which the arm is pivoted.

Such a system of endless belts and pulleys will serve to put the tool-supporter in revolution and keep it so, while it may be moved laterally or longitudinally or obliquely'over the table, as circumstances may require.

The tools are represented at E E. There may be one or more of them to thel supporter, each tool being fixed to an arm, F, which is pivoted to the supporter so as to move vertically in the are of a circle.

Figure 4 is a vertical section taken through the tool-arm, the rotary supporter, and the lower aetuating spring of the said arm.

Each arm has a lifter-rod, g, pivoted to it. This rod extends up' through the 'rotary supporter B, and the free end of. a spring, h, fixed on top of such supporter, the rod being held in connection with the spring by a nut, t, screwed on thesrod.

Furthermore, to the under side of the supporter another such spring, 7c, is fixed, its free end resting on the arm F.

A bent lever, G, pivoted to the supporter, and arranged in a slot, l, formed therein, in manner'as represented, is disposed immediately over, and has its lower or shorter arm in Contact with the upper side .of Ithe spring, the lwhole being as represented in the This cam is sustained by two slide rods m m, which are arranged in the radius o of the arm O.

A lever, I, pivoted to the said rods, and the radius c, serves to eect a vertical movement of the cam. lhe longer arm of this lever, by being sprung into either of the two notches in a holder o, xed to the radius or arranged thereon, as represented, serves to retain the cam in either of its extreme positions.

The direction of rotary motion of the supporter B, is indicated by the arrow 11 placed thereon.

While the vsupporter B is in revolution, the levers G, in succession, will be carried against the'cam, and be moved thereby so as to depress the spring under the lever, and as a consequence, cause such spring to depress the tool-arm, which will be kept depressed until the lever may have passed beyond the cam.

Immediately after the lever may have so passed the cam, the elevating-spring h will operate to raise the tool-arm upward, in a mannerto lift the tool ofi the table, or the skin thereon.

The object of thus lifting each tool is to prevent it from catching or striking against the edge of the hide or skin, soas to raise or lift the hide oli' the table.

We claim as our invention the following, viz:

The combination of the rotary tool-supporter B, and mechanism,- substantially as described, for operating each of the tools thereof in manner as explained, suchmechanism consisting of the cam H, thelever G,`the springs h and K, and the arm F, arranged and applied together as set forth.

Also, the combination and arrangement of the suprotary tool-supporter B, applied to such arm in mimporting arm C, (composed of the twoports, viz: the ner, and provided with tool-operating mechanism subradius c, and the humerus d, applied together as destantinlly as described. scribed,) with the rotary tool-supporter B md mech- CHARLES HOLMES. anism, substantially as set forth, for operating each FRANK E. HOLMES. of the tools in manner as explained.

Also, the combination and arrangement; of' the stationary bed or table A, the jointed arm C, :md the lVitnesses:
